Our longstanding support of Butterfly Conservation between 2002 and 2024, as a Gold Corporate Sponsor and through our donation of 10% of the income generated from each of our butterfly-focused holidays annually, saw us raise over £266,700 to help protect the habitats of these endearing insects. Our donations have funded a wide variety of initiatives, including an 18-month project maintain and improve a discrete area of suitable habitat for the Duke of Burgundy in the southern Chilterns.

One of the finest and most important wetland wildlife reserves in Asia, Koshi Tappu Wildlife Reserve, was created largely to protect Nepal's last remaining population of wild Water Buffaloes, but is of even greater importance to migratory birds and endangered grassland birds and mammals. In the early 1990s, it was neglected by the tourism it deserved and not regarded nationally as a tourism destination of any note. This situation changed dramatically after we conceived and funded the creation of Koshi Tappu's first luxury tented camp: Koshi Camp. Our single-handed marketing of Koshi Camp, and the attractions of the Reserve, have – nearly 30 years later – put it firmly on the map of the must-go-to destinations of naturalists and birdwatchers worldwide. The encouragement and training of local staff and expert naturalist guides has been extended to include school and village visits, emphasising the benefits of birds, wildlife, conservation and tourism for all. We were delighted to gift a 50% shareholding in Koshi Camp to the local naturalists and conservationists who assisted in establishing this popular tourist wildlife camp, and in whose hands the future of the conservation of Koshi Tappu Wildlife Reserve lies.

Such was the success of our initiative at Koshi Tappu Wildlife Reserve that, in 2008, we established a second tented camp at Suklaphanta Wildlife Reserve in far western Nepal. This remote and little-visited reserve protects the world’s largest population of the nominate race of the Swamp Deer, as well as many other mammals, including healthy populations of both Tiger and Leopard. However, it is for rare grassland birds that Suklaphanta is particularly special, amongst them the endangered Bengal Florican. It is our hope that, by encouraging tourists to this park, we will persuade both local people and the government of Nepal of the value of this important wildlife reserve. The encouragement and training given to local staff and naturalist guides has again been at the forefront of our work here.

As an associate sponsor of the annual British Birdwatching Fair at Rutland Water (the Birdfair) from 2002 to 2020, and now of Global Birdfair, Naturetrek has donated over £90,000 to the worldwide conservation causes supported by the Birdfair each year. The Birdfair is a major conservation fund-raiser, donating over £100,000 each year to a chosen area of worldwide ornithological importance identified by BirdLife International and the RSPB. Areas chosen over the years have included the Spanish Steppes, Moroccan wetlands, Spain's Coto Doñana, the Polish marshlands, Romania's Danube Delta. We have also offered tours to many of these regions in conjunction with Birdfair and BirdLife International to enable naturalists the chance to see at first hand these highly important and restricted areas and the conservation work carried out in them. On each of these tours, 10% of the tour cost has been donated to the project visited.

In 2004 we partnered with BirdLife International to raise the profile of, and raise funds for, the conservation of Madagascar’s fragile Mahavavy Delta Wetlands, an area under continual threat from draining, agriculture, hunting and over-fishing. This is the only site in the country supporting all of western Madagascar’s endemic wetland bird species, amongst them the critically endangered Sakalava Rail – at the time a bird seen by fewer than 10 living ornithologists! As well as donating £5,000 as an associate sponsor of the Birdfair, we further worked to bring wildlife tourism – and much needed finance – into the region by organising the first, expeditionary tour there in November 2004 (which was successful in seeing the Rail!). This tour brought employment and financial benefit to the local community, plus an additional £2,536 (10% of tour proceeds) which was gifted to the Programme. We subsequently ran a similar, successful fund-raising tour to the regions of Ethiopia needing assistance with the protection of habitats critical to the survival of the country’s southern endemic birds.

In April 2015, we were devastated to wake up to the news of a shattering earthquake in Nepal, which killed nearly 9,000 people and destroyed the homes of an estimated 2.4 million. Relieved to learn that all our friends and colleagues in Nepal were safe, we wanted to do what we could to help with the relief effort. We quickly established an appeal and encouraged our customers who had travelled to Nepal with us to donate to the Disasters Emergency Committee relief fund. We pledged to match all donations up to £10,000, in the hope of jointly raising £20,000 or more. We were overwhelmed by the response from our staff, friends, leaders and clients, and reached this target within 24 hours. Together, our donations and the associated gift aid raised over £40,000 for the DEC, which was used to provide emergency shelter, distribute essential food items and medical supplies, provide water filters, set up temporary learning centres and safe spaces, and ultimately go on to help with rebuilding the country’s homes and infrastructure.

In 2023, following the devastating earthquake in the vicinty of Morocco's High Atlas Mountains – one of the very first Naturetrek destinations and a region where we still have many friends and colleagues – we once again established an appeal to support the British Red Cross disaster fund. Together with our friends and clients, we raised over £22,000, which included a £10,000 donation from ourselves

In 2002 we joined forces with the Biscay Dolphin Research Programme (BDRP), putting paying customers onto a research vessel in the Bay of Biscay to fund key research into the huge numbers and variety of whales, dolphins and other marine-life realised to be using the Bay (regarded as one of the most important regions of the world's oceans). BDRP has since been absorbed into the charity MARINElife, with whom we have been working in Lyme Bay since 2008, sending records of our sightings from each of our cetacean-watching cruises into the Bay.

We established this Appeal Fund in the late 1990s in order to encourage donations from clients interested in saving the magnificent Bald Ibis, which was the most threatened species of bird in the Western Palaearctic region at the time with just 200 surviving individuals. Funds were used, amongst other things, for the purchase of a freezer – essential for storing dead birds for autopsy and other vital research! Updates on the Bald Ibis situation (now much improved), and the gathering success of researchers in saving it from extinction, were included in our newsletters, together with further appeals for funds needed.

In Nepal, we inspired and assisted local naturalists in the development of the country's first bird club, originally known as the Nepal Bird Club, and now known as BCN (Bird Conservation Nepal). BCN, now a partner organisation of BirdLife International, is committed to conservation, education, recording, research and community involvement in saving Nepal's threatened birdlife and habitats. With Hem Sagar Baral, Nepal's foremost conservationist and longstanding Naturetrek tour leader, we planned and funded the first ever BCN newsletter, and long since continued to sponsor this regular and successful newsletter.

Our annual programme of butterfly holidays has raised £266,000 for Butterfly Conservation to date between 2002 and 2024.

Our Tiger and Orang-utan tours on behalf of the EIA (the Environmental Investigation Agency) raised £53,503 between 2000 and 2011 to aid the conservation of these endangered species.

Between 2005 and 2008 we raised £14,000 for the Zoological Society of London (ZSL) by operating tours to their overseas conservation projects, which included Cheetahs in Tanzania, Vultures in India, Rhinos in Kenya, Ethiopian Wolves (in Ethiopia) and Corncrakes in Lincolnshire.
